Title: A surgical drape for transferring drive
Inventor: KEITH MARSHALL
IPC: A61B46/23
Filed: 2015-05-15
Abstract: A surgical robotic drape for enveloping an arm of a surgical robot is provided. The robotic arm comprises a drive assembly 401 to provide mechanical drive for actuating an instrument. The drape 407 comprises a covering 433 for enveloping the surgical robot drive assembly to define a sterile boundary thereover; and a plurality of interface elements 435, 437 each configured to engage with both a drive assembly interface 439, 441 and an instrument interface 443, 445 to couple the drive assembly to the instrument to transfer mechanical drive through the drape to selectively actuate the instrument. The interface elements are attached to the covering in a spatial arrangement so that each is separated from the other by material of the covering. For example, rotation of lead screw 429 may cause the carriage 421 to move in direction L1 and hence move the instrument interface 409, which moves cable 415 on pulley 411 to cause an instrument joint to bend. The covering may be flexible so the spatial arrangement may be adjusted.

Title: A capping device for wheel mounted members with an integrated reflector
Inventor: ALBERTUS ABRAHAM PETRUS DE GROOT
IPC: F16B37/14
Filed: 2015-09-18
Abstract: A dust cap (e.g. for a bolt or a nut, for mounting a wheel to an axle of a vehicle, e.g. a truck) has a safety reflector, e.g a retroreflector. The dust cap can create a warning signal to other drivers, to indicate the truck is turning (figure 12). The reflector 8 may be at an oblique angle (figures 5 & 6) to create a pulse of reflected light. The reflector 8 may be partly masked by a lip (6, figure 4), to prevent light hitting the reflector 8 in a radial direction from being reflected back, to help better alert a driver of a vehicle alongside a truck, that the truck is turning. The reflector 8 may be a film material and curved convexly. The dust cap may also have a projection 8 to indicate loosening of a nut. A projection 8 may limit the amount of loosening of the dust cap, by linking to caps (figure 10). The cap may have openings 10 for expelling water and/or dirt by centrifugal forces during rotation of the wheel, and have grooves for a form fit.
